I've always enjoyed Ranger's Apprentice, Ender's game and all affiliated books (idk if they're a series or what, but basically everything by Orson Scott Card), umm let's see... I can't think of any books, darn it! I haven't really had a chance to read since school started... Well, you could always read Sherlock Holmes (all of them), and the Iliad and the Odyssey are classics (from the classical era, I think), The Art of War (although it's less entertainment), everything by Rick Riordan, particularly that which pertains to Percy Jackson.
A book to stay away from: Into the Kingdom of Ice. I won't spoil it, in case you don't heed my warning, but it is the most depressing book I have ever read. It's a true story too, which makes it worse. But if you like the whole non-fiction thing, I'd recommend Survive the Savage Sea, and Into the Rising Sun (a collection of stories from WWII vets of the Pacific Theater), or Into Thin Air.
If you like Science, you could read A Brief History of Time, by Stephen Hawking, or The Extravagant Universe (or Our Extravagant Universe, I don't remember).
Anyway, I'll post more if I think of them.
